I just mean that when you pedal it goes without anything effort wasted. I know this is a subjective matter. My Campeon does this without being an extreme stiff ride so I know it can happen. I have a Mamasita and an El Mariachi for mtn bikes-one Scandium aluminum, one steel (both set up similar) and there is a noticeable difference when you pedal. There is a difference in the ride quality also, steel being smoother, but on the road I don't think the ride is as important as I don't plan on doing centuries on a SS. Hope that helps.
